It is generally seen as a specific developmental disorder like dyslexia.

Dyscalculia can occur in people from across the whole IQ range, often, but not always, involving difficulties with time, measurement, and spatial reasoning.

Estimates of the prevalence of dyscalculia range between 3 and 6% of the population.

A quarter of children with dyscalculia have ADHD.

Math disabilities can occur as the result of some types of brain injury, in which case the proper term is acalculia, to distinguish it from dyscalculia which is of innate, genetic or developmental origin.
